Since the beginning of the use of sialendoscopy and extracorporeal lithotripsy, recommendations have changed. The purpose of this retrospective study was to evaluate the efficiency of our treatment protocol, without a lithotripter, under general anaesthesia in the Stomatology and Maxillofacial Surgery Department of Lille University Hospital. The secondary goals were to evaluate patient tolerance and satisfaction.

All patients treated with sialendoscopy alone, sialendoscopy with a combined surgical approach or a transoral approach (TOA) (sialolithotomy) between January 2013 and December 2015 were included. Efficiency was judged by the number and size of the extracted calculi compared to those found on the preoperative CTS, the symptoms mentioned during the one month postoperative examination and the recurrence within 6 months (telephone follow-up). Success was attained when the calculus was completely eliminated and the patient was symptom free after one month and without recurrence through six months. On the other hand, failure was attained when the calculus could not be completely removed, there was remaining debris, the patient was still symptomatic after one month or if there was a recurrence before six months.

The sialendoscopy success rate was 78.57% for the submandibular gland and 92.3% for the parotid gland. We had a 100% success rate with the combined approach for the parotid gland, we had a 96.7% success rate with TOA and we had a 100% success rate with TOA assisted with sialendoscopy.

Our results conform with the literature and prompt us to suggest a protocol without a lithotripter.
